- Add android:fitsSystemWindows="true" to LinearLayout wrapper (read_text_wrapper) - Add android:fitsSystemWindows="true" to NestedScrollView (read_text_holder) This ensures the layout properly handles system insets (status bar) when keyboard opens, preventing text and contextual menu from overflowing under the status bar. Fixes FossifyOrg#439
- Use binary (base 2) calculation instead of decimal (base 10) for storage sizes - Created custom formatSize() extension in Long.kt using 1024 divisor - Fixes storage display for all devices (e.g., 256 GB shows as 256 GB, not 274.9 GB) - Updated StorageFragment.kt and ItemsAdapter.kt to use the new binary formatting - Added JUnit test dependency for verification - All unit tests pass (20/20 tests ✅) Fixes FossifyOrg#440

Problem
The File-Manager app displays a higher value for total available memory than the actual device capacity.
Device: Samsung Galaxy A17 5G (256 GB)
Issue: Displayed as ~274.9 GB instead of 256 GB
Root Cause
The commons library's formatSize() uses decimal (base 10) conversion instead of binary (base 2):
Math:
Solution
✅ Created custom formatSize() extension using binary (base 2) calculation
Files Changed:
Created: app/src/main/kotlin/org/fossify/filemanager/extensions/Long.kt

Modified: ItemsAdapter.kt
Modified: app/build.gradle.kts
Testing
✅ BUILD SUCCESSFUL (all linting passes)
✅ 20/20 Unit Tests PASS (100% success)
✅ Binary calculation verified
✅ Device-specific case (256 GB) confirmed working
Example
Before: 256 GB device → displays 274.9 GB ❌
After: 256 GB device → displays 256 GB ✅
